These cartridges work as they should at a fraction of the cost of the genuine ones. The only thing that doesn't work properly is the ink levels, but I can live without that if I'm not going to break bank on these items :)

PROS: Works as it should with one exception.

CONS: Ink level doesn't work with these cartridges.

I highly recommend these cartridges they seems to be good quality and they seems to give you the same quality print and pages as the OEM.

PROS: I bought these not knowing if they would work, but for the price I had to try them. Glad i did, what a great product works as advertised and ink lasts for a long time well worth the purchase. I just placed my second order for all the colors.

CONS: None, everything worked like it was supposed to, I have had no problems and the printer reports ink levels properly

Price!!! Only $4.39 + Canadian/Ontario taxes.
Used on a 3 month old Brother MFC-J6510DW printer.
Installed the black ink cartridge two weeks ago, print up to 50 sheets double-sided with no smearing or blurring.
It was worth the risk of spending five bucks.
I WILL be ordering the colour inks when needed


PROS: Price = $4.39 (compared to $60'ish prices in Ontario.)
Clear type, no blurring.
No discernible difference with brand inks



CONS: That I didn't know monoprice carried ink cartridges :(

maybe the batch I had was just a bad batch, because as I compared the monoprice cartridge to the brother cartridge, I noticed that a pin is missing from the middle section and that the top part of the cartridge is only half of the mold. I opened all the boxes I ordered and they were the same. I do not know how the others got their cartridges to work as my printer could close the cap because the cartridge release was not catching at all and would not snap into a position that would allow me to close it. No matter what I tried, I finally just ended up throwing away the inks as they were completely unusable. But like I said, maybe I just received the ink from a bad batch, but with that said, I don't think I'd want to try this one again, the other colors are just fine, I had no problem with them what-so-ever, just the black.

PROS: the price is excellent

CONS: there is a pin missing from the cartridge

and the top of the cartridge is only half
